RE: Is it possible to "over-scent?"
of course you can over scent... too much sent and they're going to know something is not right. plus in order to put all of that scent out you've got to go out and place it, which in turn places all of your scent out.
scents rarely work, if you're going to try some type of scent do it sparingly. once the shooting starts deer aren't going to come running into your scents; if anything use it to get a deer to stop in a shooting lane.
where are you hunting? i'm up inbemidji...
anyways, good luck
